Abstract
Synchronization of data streams is enabled. Synchronized data streams may include compressed data streams. Conventional data compression components may be utilized to generate the compressed data streams. As an example, compressed digitized video and associated metadata may be synchronized in this way. Synchronization may be enabled based on causing data compression components to generate detectable data units. For example, patterns of data units having well characterized entropies may be passed through data compression components to generate detectable patterns of compressed data units.
